【摘要】 在研究雌株蓖麻遗传规律的基础上,利用其人工诱导条件下可发生育性逆转的特性,创建了核遗传型模拟三系配套的杂种优势利用技术体系,育成了雌株率达100%的蓖麻雌性系8937F及其保雌系,并培育出高产杂交种汾蓖5号、6号等投入大面积生产试种.更多还原

【Abstract】 A technical system of heterosis utilization about the simulating three-line of nuclear genie type was founded, on the basis of research about the genetical behavior of pistillate castor and the trait of sexual reversal under artificial inducing condition. Not only the pistillate line 8937F whose rate of pistillate plants is 100 percent and its maintaining-pistillate line, but also hybrid crosses of high yield Fenyang Castor No. 5 and No. 6 have been bred. The hybrids have been planted on a large area.更多还原
